Pinebook Pro refuses to boot from eMMC

[pivic]

Thanks a lot for your kind response.

Since I did all that I described there, the computer won't boot at all, which is a shame. I've tried maybe ten different distributions and versions—all, according to the Pine64 software-wiki page, OK for boot via SD/eMMC—but sadly, the computer won't start at all.

By this, I mean there's no starting lights going on at all. The only light that comes on is the red light that goes on when the machine is charged; I left it charging for a few hours, both via the Pine64 charger and via USB-C, so I'm quite sure the battery's charged.

I tried using the reset button, and nothing happens. I've used three different MicroSD cards (which have all worked on the computer in the past).

Either the computer is fed up with me, I've destroyed its ability to boot from MicroSD by what I've done so far, or there's another way to salvage this. I hope you guys feel the energy to come up with some kind of tip because I'm at my (already tiny) wit's end here. Please, if you can, run a tip by me. Thanks.

That sounds more like your PBP had its battery completely drained. Unfortunately, if it was drained dead then you'll need more than a few hours to get it charged enough to boot again. Try 6-8 hours of charge time. When I do that, I let mine charge for at least 8 before attempting to boot. Since the PBP has a low draw, even for charging, it takes a lot longer than conventional laptops to recharge.

You may also need to hold the power button for a few more seconds after it gets charged back up.

Thanks a lot! I charged it overnight (10 hours) but still nothing happens (and I've tried all cards).

I'm trying out what @KC9UDX Just mentioned, i.e. to charge it using only a USB-C charger. I'll try to start the computer after it's charged for a few hours and I'll remember to press the On button a bit longer than usual. I've also used the hardware-reset button some times, previously.

The red light switches on when I'm charging it (both via power cable and USB-C), so that's good, at least.

Still, I'm fearful that something has happened. I've checked every cable and every connector that I can find on the motherboard, but nothing seems to have come loose.

Thank you so much for your help so far, guys. I really appreciate it,
